What is effective in dissolving paint

How can I get rid of the rust on the iron paint bucket - hydrochloric acid, acetic acid is too weak! For example, 1mol L of FeCl3 solution pH = and the most concentrated can only reach pH = hydrolysis is more powerful than acetic acid ionization! But this scheme is not good, hydrochloric acid is too acidic and may cause damage to the tile, and the reaction is relatively slow, it is recommended to use oxalic acid, (toxic, but not very toxic) due to the generation of ligand ion [Fe(C2O4)3] - the reaction is relatively fast For example:

It is also a common reagent that is easy to buy) The use of oxalic acid in printing and dyeing (1) It is used as an agent for washing rust spots on fabrics, and iron is affected by oxygen and water in the atmosphere to generate complex compounds, which are called rust. The composition of rust varies depending on the condition in which it is generated, but rust contains ferric ions. Rust spots on the cotton fabric form defects that must be removed.

Oxalic acid is an effective agent for washing off rust spots on cotton cloth. The principle is roughly that oxalic acid can form an iron oxalate anionic chromium complex [Fe(C2O4)3] with ferric ferric ion fe - this anionic complex is easily soluble in water, so the rust can be washed with oxalic acid. The dosage of oxalic acid is 20 g liters, and acetic acid (98%) is about 30 ml liters.

Oxalic acid is easy to damage the fiber, and after the cotton cloth is treated with oxalic acid, the oxalic acid remaining on the cotton fiber needs to be thoroughly washed with water. If it is not washed, when the cotton cloth is dried, the dilute oxalic acid solution will turn into concentrated acid, which will quickly and seriously damage the fibers and cause holes, so you must pay attention to it. Rust spots on nylon fabrics can cause yellowing of fabrics, which can also be removed with oxalic acid.

Paint stains: Fresh paint can be made with turpentine and banana water.

Solvents such as benzene carbon tetrachloride are erased. Stale.

The dirt can be immersed in ammonia water of 10 20.

or borax solution to dissolve the paint and remove it. It is also very effective to soak the stain in a mixture of 1:1 ether and turpentine, soak the stain, and then wipe it with gasoline.

Butyl acetate and acetone, these two solvents have very low toxicity and more importantly, great solubility.

The thinner is also the water of the day.

The ingredient of nail polish remover is how to clean the paint that can dissolve the paint1Olive oil: If you have olive oil at home, rub some of the paint on your hands a few times, soak it well for a while, and wash it with soap after a few minutes to avoid hurting your hands.

2.Toilet water: If you can't find olive oil, you can always have it!

Apply toilet water to the area where the paint is wet. After a while, wash it with soapy potatoes and it will be clean. 3.

Peanut oil & salad oil: If you don't have the above two things, then use peanut oil or salad oil, rub it on the place where the paint is stained, add some dish soap to rub it, and finally rub it twice with a rag, and the paint will always be removed. 4.

Banana oil: If you are afraid of a strong smell, you can use banana oil to wash it on the area where it is stained with paint. There will be no odor with banana oil.

Or go straight to the paint shop and buy some turpentine for cleaning. 5.Gasoline:

The last trick is more painful, which is to use gasoline to clean. Apply a little petrol to the area where the paint is stained and wash it with soap. 6.

Cool oil > lard: Identify what kind of paint you are getting on first. If it is an ordinary water-soluble paint, it can be removed directly with water, and the clothes are more expensive to avoid affecting the texture, and the non-water-soluble paint can be directly applied to the paint with the cool oil used to repel mosquitoes, and every few minutes, wipe it with a cotton ball along the lines of the clothing, and then wash it with water.

If the nylon fabric gets painted, it is recommended to scrub it with lard and then wash it with laundry detergent. 7.Water-soluble paint:

Water-soluble paint, latex paint, etc. Solvent-based paints: Yongming paint, Sanbao paint, etc. 8

Liquor + Alcohol: If you accidentally get on latex paint and leave a mark, you can take advantage of it and it also has the ability to dissolve in a variety of solutions. Use its own characteristics to find a way to remove it.

You can use a mixture of 60 liquor or 8:2 alcohol (95%) and water to soak the white latex stains on the clothes, and after soaking for about half an hour, you can scrub with water until it is clean, and finally rinse with water. 10.

Wind oil essence: There are wind oil essence at home, take a small amount of wind oil essence and apply it to the paint stain, rub it back and forth a few times, and the paint will fall off. Then wash the skin with clean water and serve it clean.

It's better to use wind oil essence than gasoline, after all, the taste is not so big.

Theoretically, hydrocarbon solvents such as methylene chloride, tetrachloroethylene and xylene have good swelling and solubility for most polymers, followed by non-polar solvents such as esters, ketones and ethers, and alcohol solvents such as methanol and ethanol have the worst potency.

Each paint will have a corresponding thinner. For example, water-based paints can be dissolved with water or alcohol solvents; Phenolic and alkyd acids can be dissolved with 200 gasoline or benzene; Epoxy, acrylic acid, and nitro can be mixed diluents prepared from one or several organic solvents such as esters, alcohols, ketones, and benzene.

Fire safety is flame retardant methylene chloride or carbon tetrachloride, followed by strong solvents such as xylene, cyclohexanone and ethyl acetate. Two-component phenolic, epoxy and polyurethane are no longer soluble in general organic solvents after polymerization and curing, and need to be formulated separately.

1. Paint stripper 2. Acetone water 3. Butyl water 4. Nitro paint thinner 5. Gasoline 6200 Solvent oil The above kinds are easy to buy in the market.

Chemicals can melt rod fishing, some I think you can use alcohol, the dissolution effect of alcohol is still very good, it can better dissolve alcohol, this should be able to achieve a better cleaning condition.
